queryparam

Documentation

Overview

Package queryparam provides utilities for efficiently working with query parameters in URLs. It focuses on zero allocation URL query parameter lookups.

func handler(w http.ResponseWriter, r *http.Request) {
	// Get the value of the `key` query parameter.
	value := queryparam.Get(r.URL.RawQuery, "key")
}

Note that this method does not support multiple values for the same key, so using `val=1,2,3` is preferable to `val=1&val=2&val=3`.

Functions

func Get

func Get(query, name string) string

Get a query param by name without any dynamic allocations. For small numbers of query params, it is faster to call this method multiple times than to use `url.ParseQuery` and then call `Get` on the resulting `url.Values`. This method does not support multiple values for the same key, so using `val=1,2,3` is preferable to `val=1&val=2&val=3`.
